Seven Kingdoms: Seowyn's Crossing
Gwyllan’s Watch is the capital of Tavanion, the seat of power of the eladrin-in-exile. It is named for Gwyllan ap Kadishai, the mage-king who founded the city, sometimes called the first Esavol of the eladrin-in-exile following the Feywar.
This magnificent city of pearl, silver, and white marble stands on a high rocky cliff overseeing the Sea of Sunken Fires. It is also partially built on several islands below, often connected to the main city by high arching white bridges. It lies partly in Tol and partly in the Feywild.
